The present disclosure is drawn to polyurethane dispersions. In one example, a polyurethane dispersion can include a polyurethane with a polymeric ionic side chain and a polymeric non-ionic side chain. The polyurethane can be formed of polymerized monomers including a diisocyanate, a first polymeric diol, and a second polymeric diol. The first polymeric diol can include a first polymer chain replacing a hydrogen atom of a thiol group of a 1-thioglycerol molecule. The first polymer chain can include a block of a polymerized ionic group-containing vinyl monomer. The second polymeric diol can include a second polymer chain replacing a hydrogen atom of a thiol group of a 1-thioglycerol molecule. The second polymer chain can include a block of a polymerized non-ionic vinyl monomer, and the second polymer chain can be devoid of ionic groups.

Provided herein is a method of forming a three-dimensional object in which the polymerizable liquid includes a mixture of (i) a light polymerizable first component, and (ii) a heat polymerizable second component; the heat polymerizable second component comprising (i) a first blocked reactive constituent that is blocked with a volatile blocking group, and optionally (ii) a curative. Upon heating a formed three-dimensional intermediate sufficiently, the volatile blocking group is cleaved and vaporizes out of the three-dimensional intermediate, to form the three-dimensional object. Also provided is a three-dimensional object produced by the method. Further provided is a polymerizable liquid composition useful for carrying out the method, and prepolymers and monomers useful for the polymerizable liquid composition.
